IMPROVEMENT IN SURGEONS NEEDLES.

Specification forming part of Letters Patent No. 221,638, dated November11, 1879; application filed July 21,1879.

To all whom it may concern:

Be it known that I, JOHN WATSON, of the city of Utica, county of Oneida,State of New York, have invented certain new and useful Improvements inSurgeons Needles; and I do hereby declare that the following is a full,clear, and exact description'of my invention. which will enable othersto make and use the same, reference being had to the accompanyone endsharpened and the other out square A hole is boredjat the latter endlongitudinally into the Wire by a suitable drill or tool placed in thecenter of the straight out and continued any required distance-say,oneeighth of an inch, more or'less. Through the side of the needle, at adistance from the straight out corresponding to the length of the saidhole, is transversely bored 2. second hole by a suitable tool or drill,thus penetrating the wall of the hole in the needleyand causing the Thetool or drill for the tir'sthole may be so formed that'ihis hole in thecenter of the needle will be a true oylindricalbore, or they may be madeto produce a conical bore, as may be desired. The second hole, also, maybe of any desirable bore, and the angle formed between-the axes of theboreslof the two holes may be right or obtuse. The side hole is madewith beveled walls, or a countersink, so as to catch and hold the knotin r the thread while the knot is yet below the surface of the needle,thus facilitating the stitching at the same time that the thread is heldsecurely in the needle.

When a thread of any required material, such as silk, cotton, or linen,is to be used, a knot is made at one end of the thread, and theotherend, being pointed, isintroduced through the hole in the side ofthe needle, and pushed through the hole in the center of the needle, iscaught at the pointed end by the fingers, and drawn out until the knotissnugly embedded in the hole in the side.

The needle can be operated with like an ordinary needle.

Referring to the drawings, in order to explain my invention more fully,Figure 1 is a side view of my improved needle with-thread attached. Fig.2 is a longitudinal sectional view, and Fig. 3 is a top View, of thesame. Fig. 4 is a section, showing the countersink in the horizontalhole.

A is the needle, with the pointed end I). O is the hole in the top andthrough the center of the needle. 01 is the hole in the side of theneedle. E represents the thread with the knotted end g.

The shape of the needle may be either straight or curved, according torequirements.

When, instead of a fibrous thread, a wire is used, the latter may beknotted by fusing a head on its end in a flame.

I am aware that needles have been made somewhat similar to mine, onehaving side
